Not sure where this comes from. He loved John Wolford, gave chances to Bryce Perkins, started Brett Rypien and drafted Stetson Bennett, none of which have/had big armMcVay needs/likes guys with big arms..

Levis is going on the last year of his rookie deal, could be a Garoppolo replacement and they could still draft a QB if they liked the potential
